| 摘 要： | 剩余油饱和度的计算是油田开发中后期测井评价的重点和难点.注水开发的涠洲W油田由于油层水淹程度不同,地层水矿化度变化较大,因而不同时期、不同区块的地层水电阻率成为剩余油饱和度计算准确与否的关键参数.对于水淹层,利用产出水矿化度随含水率(即水淹程度)的关系确定地层水电阻率；对于未水淹层,采用纯水层计算地层水电阻率.利用实际... |
| 关 键 词： | 剩余油饱和度 地层水电阻率 水淹层 含水率 岩电参数 |

| Abstract: | Residual oil saturation calculation was the key point and difficulty of logging evaluation at the middle and late stages of oilfield development.Because the oil reservoir salinity changed greatly in formation water,the resistivities in different times and different blocks became the key parameters of residual oil saturation calculation.For the water flooded reservoirs,the relation of salinity of produced water and water content(water flooding degree) was used to determine the formation water resistivity,for... |
| Keywords: | residual oil saturation formation water resistivity water flooded reservoir water content litho-electric parameter |
